Application filed February 17, 1908. Serial No. 416,354. I

To all whom it may concern:

Be it known that I, EUGENE MURRAY, a citizen of the United States, residing at Washington, in the. District of Columbia, have invented certain'new and useful Im-. provements in Pneumatic Cotton-Pickers, of which the following is a specification.

My invention relates to cotton pickers and more especially to that class of cotton pickers employing air as the operating me dium, and the object thereof is to provide a novel construction which will be simple and inexpensive to manufacture andetficient and durable in use.

A further object of my invention is to 'provide'mechanical picking elements operated by the air, in combination with means to preventthe contact of the cotton, before used to designate like parts throughout the several figures, and in which, I

Flgure 1 1s a longitudinal sectional View of a'picking head constructed in accordance with my invention, Fig. 2 is a cross sectional view taken therethrough on the line 2-2 of Fig. 1, and Fig. .3 'is a similar View taken therethrough on the line 33 of Fig. 1.

In the practical embodiment of my invention I provide a picking head comprising an outer stationary cylindrical casing 1 open at its outer end and provided with a reduced inner end 2 adaptedto receive one endof an air hose attachedat its other end to an exhaustingfan or the like for sucking the air inthrough said head and said hose. The outer open end of said casing is preferably strengthened by an internal supporting ring 3.

Within the casing 1 and adjacent its point of reduction to form the end 2 is a spider 4 having acentral annulus 5 surrounding and supporting the inner extending end of the picking tub'e 6. Thepicking tube 6 is of greatly reduced diameter n comparison to the outer casing 1 and is concentrically tnounted therein. Mounted about the pickmg tube 6 and of slightly reduced diameter in comparison to the outer casing 1 is a tubular picker caslng 7 concentrlc with said outer casing and said picking tube andthereof. A protecting tube 12 surroundsthe outer end of said picking tube 6 beyond the ends of the casings 1 and 7, and is, provided with. an offset flange 13 abutting the flange 10 of the picking tube and with a circular curved outstanding flange 14 covering the mouths of the casings 1 and 7 in spaced relation, to allow of the entrance of air, and secured to the outer casing 1 by brackets in the form of bolt bars 15 connected-to and.

extending from said casing 1, and-passingthrough the said flange, said bars being threaded for the reception of nuts 16 upon the outer face of said flange. The abutting flanges 10 and 13 of thepicking tube 6 and the protecting tube 12respectively and the annulus 5 and the portions of said picking tube adjacent the same are formed to receive balls 17 therebetweento allow of free rotation of the picking tube 6 and its casing 7. Such rotation is efl'ected by means of, oppositely disposed and spirally curved vanes 18 disposed between said tube 6 and its casing 7 andacted upon by the air drawn through the open end of said casing 7 which is protected from the entrance 1:.- any of the cotton by the curved covering Ilange 14..

In operation, the air hose having been attached :to the reduced end 2 of the stationary casing 1, the end of the picking tube 6 is guided by the operator upon the cotton boll which is torn from its pod by the revolving fingers 11 and is sucked through the tube 6 and through the hosewithout coming into contact with any of the'operating parts. Such a-constructlon as I have shown will be simple and lnexpenslve to manutacture,

-I claim as new and desire to secure bv Let ters Patent 1s:

'2. A nozzle for pneumatic cotton picking apparatus comprising a casing, a revolving cylinder within said casingya picking tube, and means for revolving said cylinder and said tube. a

3. A nozzle for pneumatic cotton picking apparatus, comprising a casing, a revolving cylinder within said casing, a picking tube, and blades secured to said cylinder for re; volving the same and said tube.

4. A nozzle for pneumatic cotton picking apparatus comprising a casing having air inlets, a cylinder revolubly mounted in said casing, a picking tube, and means operated by the air suction to revolve the cylinder and picking tube.

5. The combination in a device of the character described, of a rotatable picking tube, and picking fingers extending in- Wardly and curved rearwardly from the forward end thereof, and means for causing a current of air therethrough.

6. The combination in a device of the character described, of a rotatable picking tube, having integral picking fingers extending inwardly, and curved rearwardly, from the forward end thereof, and means for causing a current of air therethrough.

7.
